"Solidarity" is but an empty ideology if one limit it to human species. There is no abyss between man and animal; the two domains are separated by a tiny rivulet which a baby could step over. We are animals, we live on animals, and animals live on us. We both have and are parasites. We are predatory, and we are the living prey of the predatory. And when we follow the love act, it is truly, in the idiom of theologians, more bestiarum. Love is profoundly animal; therein is its beauty. CHAPTER II THE AIM OF LIFE The importance of the sexual act.--Its ineluctable character.--Animals who live only to reproduce themselves.--The strife for love, and for death. --Females fecundated at the very instant of birth. --The maintenance of life. What is life's aim? Its maintenance. But the very idea of an aim is a human illusion. There is neither beginning, nor middle, nor end in the series of causes. What is has been caused by what was, and what will be has for cause the existent. One can neither conceive a point of rest nor a point of beginning. Born of life, life will beget life eternally. She should, and wants to. Life is characterized on earth by the existence of individuals grouped into species, that is to say having the power, a male being united with a female, to reproduce a similar being. Whether it be the internal conjoining of protozoaires, or hermaphrodite fecundation, or the coupling of insects or mammifers, the act is the same: it is common to all that lives, and this not only to animals but to plants, and possibly even to such minerals as are limited by a non-varying form. Of all possible acts, in the possibility that we can imagine, the sexual act is, therefore, the most important of all acts. Without it life comes to an end, and it is absurd to suppose its absence, for in that case thought itself disappears. Revolt is useless against so evident a necessity. Our finikin scruples protest in vain; man and the most disgusting of his parasites are the products of an identical sexual mechanism. The flowers we have strewn upon love may disguise it as one disguises a trap for wild beasts; all our activities manœuvre along the edge of this precipice and fall over it one after another; the aim of human life is the continuation of human life.
